In order to rework some of the persistence layer I would like to move around some of the files first, keeping job specifics in a jobs folder. Having some of the items which are root level taskflow items (flow, task) be at the root of the hiearchy. Also for now until the celery work is commited move that, since it doesn't make sense in backends anyway. Change-Id: If6c149710b40f70d4ec69ee8e523defe8f5e766d
